To all whom, it may concern: 13, which is provided on opposite sideswith Be it known that we, ORREN I. SEARLES, arms 14:, to which arepivoted levers 15, the GEORGE F. JACKSON, and FRANK M.

The upper valve 21 isadjustable upon plate and is provided with downwardly-exthe upper end ofthe valve-rod, which is tending legs 7. The upper end of the saidscrewthrezuled, as shown, and provided with 0 4o yoke or bail isprovided with a socket S, in clampingnuts 27 for this purpose.

The upbelow the feet 7 at the lower ends of the arms 45 per endof said cylindrical casing is provided of the yoke-or bail. The deviceis new lowwith a head 11, provided on diametrically-opered by means ofthe handle 9 into the cisposite sides with perforated lugs 12,engagtern. \Vhen the bottom is reached, the foot ing the opposite sidesof the yoke or bail 6, 22 on striking the bottom will be forced withupon which the said cylindrical casing is the valve-rod 1S and thevalves in an upward [O0 50 thus adapted to slide. The head 11 of thedirection, thus causing the water and accucasing 10 is provided with aswiveled handle mulated filth at the bottom of the cistern to rush intothe casing 10, while the air confined in the latter escapes through theopening 20 and upwardly through the water in the cistern, which is thusaerated and purified. The device is now hoisted out of the cistern, andthe contents of the casing 10 is discharged by raising the latter uponthe yoke or bail, after which the operation may be repeated.

The feet 7, extending downwardly below the bottom plate, will preventthe latter from coming in contact with the bottom of the cistern andthus interfering with the successful operation of the device.

By means of the jointed handle the device may be successfully used forcleaning cisterns located in places not otherwise easily accessible.

Having thus described our invention, what we claim is 1. In a deviceforcleaning cisterns, the combination of a yoke or bail, a bottom platemounted permanently near the lower end of the same and having a centralopening, a eylindrieal casing mounted to slide upon the said yoke orbail and having an open lower end adapted to engage the bottom plate andprovided with an opening in its upper end or head, a valve-rod extendingvertically through the cylindrical casing and bottom plate and havingvalves adapted to close the openings in the head of said cylinder and inthe bottom plate, and a handle attached to the yoke or bail,substantially as set forth.

2. In a device for cleaning cisterns, the combination of a cylindricalcasing having a valve-opening in its head or top plate and mounted toslide upon a suitable yoke or bail, a bottom plate secured nearthe'lower end of said yoke, having a valve-openin g and adapted to closethe lower end of the casing, means for securing the cylindrical casing,when in engagement with the bottom plate, to the yoke or bail, and avertically-sliding valverod extending below the bottom plate and havingvalves adapted to close the openings in the said bottom plate and in thehead of the cylindrical casin substantially as set forth. 1

In a device for cleaning cisterns, the combination of the cylindricalcasing mounted slidingly upon a suitable yoke or bail and having avalve-opening in its head or top plate, a bottom plate secured near thelower end of said yoke, and having a valve-opening and an annularshoulder or rabbet engaging the lower end of the cylinder, feetextending downward below said bottom plate, valves arranged to close theopenings in the bottom plate and in the top of the cylinder, and meansfor operating said valves, substantially as set forth.

4. In a device for cleaning cisterns, the combination of thecylindricalcasing having an air-exit in its upper end, the bottom plate having theinlet or opening surrounded by an upwardly-extending annular taperingflange, a vertically-sliding valve-rod having valves adapted to closethe inlet-opening in the bottom plate, an air-exit in the top of thecylinder, and a handle by which the device may be manipulatedindependently of the valverod, substantially as set forth.

5. The combination of the yoke or bailhaving the bottom plate, thecylindrical casing mounted to slide upon said yoke by means ofperforated lugs or ears, a handle swiveled centrally upon the top plateof the cylinder and having arms extending in opposite directions, androds or levers connected pivotally with said arms extended throughperforations in the lugs at opposite sides of the cylinder-head andadapted to engage recesses or perforations in the yoke or bail,substantially as set forth.

6. The combination, with the bottom plate having the inlet-opening andthe cylindrical casing, the two being separably connected, of avertically-sliding valve-rod having valves adapted to close theinlet-opening in the bottom plate, below which said valve-rod extends,an air-exit in the top of the cylinder, and a handle for manipulatingthe device independently of the valve-rod, substantially asset forth. x

-7. The combination, with the cistern-cleauing device comprising thebottom plate having the inlet-opening, the yoke or bail attached to saidbottom plate, the cylindrical casing mounted slidingly upon said yokeand having the vertically-sliding valve-rod provided with valves toclose the inlet-opening in the bottom plate, and an air-exit in the topof the cylinder, of a jointed handle mounted in a socket at the upperend of the yoke or bail and having a sliding sleeve, substantially asand for the purpose set forth.

In testimony that we claim the foregoing as our own wehave heretoaffixed our signatures in presence of two witnesses.
